Fabric covers, because they help control the process, offer a spectrum of benefits to raise quality, consistency, and predictability in the finished compost product. Those benefits include:
- Moisture management — If the climate is wet, excess moisture is kept out of the windrow; if the climate is dry, moisture is retained within the row.
- While shedding rain, gaseous exchange is still permitted.
- Nutrient retention is higher in covered compost than uncovered.
- The compost cycle will finish sooner.
- Ultra-violet ray damage is minimized.
- Covered compost retains temperature levels better than uncovered. In freezing conditions, covered compost does not freeze as deeply during winter and warms faster in spring.
- Leaching is significantly reduced when compost is covered.
